A able stencil and I impart rotary and, if de- I tion and forming aotesired, alsotransversal movement to all the pencils, at the same timeapplying colour to those parts of the pencils, which are not covered bythe stencils.

Any su1table means mafy be provided for applying colour, but pre erablythefcolour is applied by sprayingSK In the drawlngs a ed to thisspecificapart thereof a device embodying my invention and specimens ofpat-` terns obtainable thereby are illustrated diagrammatically by wayof example.

In the drawings l Fig. 1 is an elevation of a stencil and a pencil readyfor insertion therein.

Fig. 2 is a cross section of a device for imparting transversal androtary movement toV the pencils,

Fig. 3 is a the device,

Figs. 4 and 5 illustrate specimens of patrns Referring to the drawingsand first to Fig. 1', 1 is a stencil, 2, are rings-fixed to the ends ofthe stencil, and 3 is a lead-pencil, to

In the practice of my invention I arrange plurality of stencils,

impart rotation and, if desired, also reciprocation to the stencils andapply colour to the uncovered parts of the pencilswhile they arebeingmoved. After a predetermined pattern has been produced, thestencils may 847,229, and in Germany October 29, 1927.

be exchanged for other stencils, for instance, a stencil havingleft-handed thread may be substituted for one having a right-handedthread. In this manner the chequered pattern shown in Fig. 4 isobtained, while Fi 8 illustratesa pattern obtained with a sing e stencilas shown in Fig. 1.

The stencils may be caused to rotate without reciprocation or they maybe displaced or reciprocated while rotating. It is not always necessaryto reciprocate the stencils as a single dlsplacement at right angles totheir axis may suice for the production of the desired pattern.

During rotation and/or reciprocation of the stencils colour is appliedto them prefer- 1 ably by spraying. The spray is simultaneously appliedto several juxtaposed pencils ut in order to place a given number ofpencils within reach of the spray the blanks may be displaced with resect to the spray nozzle, or the nozzle wit `r both may be displaced. Inperforming the method with a movable spray nozzle the stencils arevpreferably moved in one direction only, for instance by a conveyer,while reciprocating movement is imparted to the stencils, when the spraynozzle is fixed.

Referring now 'to Fig. 2, 8 is a frame, 7 is a slide adapted to bereciprocated on the frame by hand or by any suitable mechanism (notshown), 6 is a fixed plate inserted within the slide which is channeledfor its reception, 5, 5 are races`on the fixed plate 6, and 4, 4 arenotched plates on the upper edges of the slide 7, The stencils 1encircling the pencils 3 are inserted with their rings 2, 2 in oppositenotches of the plates 4, 4. When the slide is reciprocated the stencils'are entrained by the notched plates 4, 4 and at ,the same time' rotatedby races 5, 5 on the plate 6, while colour is sprayed onto the pencilsfrom the nozzle 9.

Any suitable means other than the .rings ,2 may be provided for holdingthe pencils desire to be limited to the exact details of constructionshown and described for obvirespect to the spray, y
